Ladder Logic Configuration Examples

Publication 1746Ć6.8 - April 1997

Procedure

1. Create integer file N10. Integer file N10 should contain eight

elements (N10:0 through N10:7).

2. Enter the configuration parameters for all eight analog input

channels into a source integer data file N10. See Appendix B for
the channel configuration worksheet.

3. Program a rung in your ladder logic to copy the contents of

integer file N10 to the eight consecutive output words of the
1746-NI8 analog module beginning with word O:3.0.
